On the taskbar, click the Start button, point to Programs and select VALCOM V-2924sc
Programming Tool.
The V-2924 Programming Tool splash screen appears momentarily and then the Programming
screen comes into view.
System Configuration
To begin the programming process, click on File. A pull-down menu appears allowing selection of a previously
programmed file (click on Open) or the ability to create a new file (click on New). The following instructions
assume a New configuration file is being created. Click on New from the pull-down menu. A System
Configuration screen is displayed to allow selection of the installed components within the system.
Select one of the following from the list:
 For a 24-station system select Main Board.
 For a 48 station system select Main Board + Expansion 1.
 For a 72 station system select Main Board + Expansion 1, 2.
 For a 96 station system select Main Board + Expansion 1, 2, 3.
Click in the box next to Clock Board if the V-2927 Clock Control Card is installed.
Press OK to accept the present selection or Cancel to re-select. When selection is complete, the Programming
Window Screen will be displayed. (To display the configuration of the system press the Details button).
4
When OK is selected from the System Configuration screen, the Programming Window appears - see below. The
Programming Window allows each option to be accessed by selecting the option and pressing Open or by double
clicking on the selected option. All functions can be listed at once by pressing Open All. (All of the options
accessed through the Programming Window can also be accessed from the pulldown menus).
5
Architectural Number and CLID (Caller ID) Programming
The first function to configure is the Architectural Number and CLID Programming.
The Architectural Number is a 1 to 4 digit number that is dialed by the phone to connect to a specific speaker.
Flexible architectural numbering is often selected to allow speakers and room numbers to match. The CLID
Programming allows a name or up to 15 characters description to be entered for each station.
The information entered in the CLID description field will be displayed on the phone or Caller ID unit if provided as
part of the system.
The Edit Station Entry allows a CLID description to be entered for each station. Example: 105 would be the
Arch # and MR. HALL would be the CLID description (15 character limit).
The Delete Station Entry allows removal of selected architectural and CLID descriptions.
Auto Numbering assigns the Arch # in sequential order. The beginning number is the currently selected station;
an ending number must be specified.
To Auto Number – Highlight station where architectural numbering begins.
Select Edit Station Entry. Enter beginning architectural number and select OK.
Select Auto Numbering and enter last architectural number (must be a higher number).
Select OK.
Enter information for the Main Board as well as each Expansion Unit being used and press OK to accept.

COMMUNICATING WITH THE V-2924A
Communicating with the V-2924A allows sending and receiving of user programmed data, Setting of
System Date and Time and reading the revision numbers of the system firmware.
Once system programming is complete, this data must be downloaded to the V-2924A System. This
communication can be accomplished through two methods:
Initiating Communications
Direct Connect (PC is on site with the V-2924A System - can be accessed via a Null Modem RS232 cable).
To Connect:
Connect null modem cable from the V-2924A to the PC being used.
Set up Com Port (page 15).
Connection complete.
Modem Connect (PC is off site or can only be accessed using phone lines to communicate).
To Connect:
Set up modem (User required procedure - page 15).
Set up Com Port (page 15).
Select Dialing Method:
 Modem Connect (page 15)
 Manual Connect (page 16)
REMINDER:
For a modem to communicate with the V-2924A, there must be a remote modem connected to the
V-2924A. See page 18 for Setup of the Remote Modem.
Serial Port The serial port on the V-2928 Option Board is set for 9600 bits/second, 8 data bits, no parity and 1
stop bit (9600-8-N-1). The serial port properties of the connected PC or modem must be set to match these
parameters.
Direct Connect - Set Up Com Port
Select File, Com Setup, Com Port Selection.
If the port is known, use the down arrow to locate the number, select it and press OK.
If the port is not known, select Auto Find.
Reminder:
If direct connect is being used, make sure cables are connected and V-2924A is on.
If modem connect is being used, make sure modem is installed and working properly.
Modem Connect
From the Programming Tool, select File, Modem and then Modem Connect.
The screen below appears. Enter the number to dial or select a phone number from the list displayed.
Numbers can be added, edited or deleted from the list. Up to 10 numbers can be stored.
15
Once the desired phone number is displayed in the Number to Dial field, click on the Dial button. Messages
should be displayed stating, "Initializing", "Dialing" and "Modem Connection Successful". Click on OK.
If modem fails to connect, verify modem was set up properly during system installation. Refer to section titled,
"Setup of the V-2924A Modem," page 18.
Manual Connect
From the Programming Tool, select File, Modem and Manual Connect. Follow the instructions as described
on the screen. Messages should be displayed stating, "Initializing", "Dialing" and "Modem Connection
Successful". Click on OK.
Send data to V-2924A
From the main menu, select Send Data to V-2924. If a file is open, that file will be sent to the V-2924A System.
If no file is open when Send Data to V-2924 is selected, the screen appears to allow selection of the data file to
be opened and downloaded to the V-2924A. Highlight the desired file and click on OK.
16
Receive Data from V-2924A
From the main menu, select Receive Data from V-2924. This will take place automatically. If you are not
allowed to select Receive Data from V-2924, close the currently open file and try again. Messages will be
displayed stating Receiving Data, Receive Data Completed Successfully. Click on OK.
Set System Date and Time
Set System Date/Time by clicking on the Date/Time pull-down menu. Up/Down arrows are used to move date
and time to the desired setting. Press Update to set the new Date/Time or Cancel to leave unchanged. The
Automatic DST Adjustment can be enabled or disabled here. The DST correction is based on the pre-2007
rules (first Sunday of April, last Sun of October) therefore it is recommended to not enable the Automatic DST
Adjustment.
